A Study On The Relationship Between Occupational Stress And Work Ability Of Workers Exposed To The Low Dosage Ionization Radiation

Objective: To test the effect of low dosage ionization on the health of professional personnel.Through examination of physiological function, psychological stress and the work ability of the low-dose ionizing radiation workers, we analyzed the relationship between the individual dose of radiation workers and health lever, occupational stress, work ability; To approach occupational stress and its influential factors in radiation workers.To provide the basis for protecting physical and mental health of radiation workers. Methods: Occupational stress inventory revised (OSI-R) and work ability index (WAI) were used to measure the different types of radiation workers in 557 (exposed group) and 389 non-radiation exposure workers (control group). 460 radiation workers were selected, and their individual dose was detected by luminescence method.They were divided into high,medium and low dose group according to different dose levels;ocular lens and hemograms were analyzed by routine method; Agar diffusion method of immunoglobulin; T3, T4, TSH detection of RIA; biochemical test of blood glucose, blood lipids; chromosome aberration were examined using the whole blood of tiny culture method. Results: 1)Per capita annual average dose equivalent was 3.48±1.33mSv, and per capita annual dose equivalent of different types was significantly different (P<0.01).2) Physiological function: Of different working age, their rate of lens opacities was significantly different (P<0.01); Different dose group and the different working age, chromosome aberrations rate had a significant difference (P=0.000);Other indicatrix, the different dose levels of IgG and TC had a significant difference (P<0.05);TC and TG of different working age had a significant difference (P= 0.000).3)Occupational stress: the scores of ORQ, PSQ, PRQ (except for SS) from exposed group were higher than the controls (P<0.01); the scores of ORQ, PSQ, PRQ of different dose in exposed group were higher than the controls (P<0.01); different working age, the score of ORQ upgraded with the increasing of working age (P<0.01); the scores of all items of PRQ and PSQ (except for RI) were positively correlated (P<0.01), and the scores of all items of PRQ and PSQ were.○4The work ability: the WAI score of control group was higher than the exposed group (P<0.05); in "poor"WAI score, exposed group was higher than control group; in "good" WAI score, exposed group was lower than control group, (P<0.05); in middle dose group, WAI score was lower than control group (P<0.05); the WAI swore was decreaced with the increasing of working age (P<0.05).○5The score of WAI was negatively correlated to ORQ and PSQ (P<0.01), and positively correlated to PRQ (P<0.01), ORQ was positively correlated to PSQ (P<0.01), both negatively correlated to PRQ (P<0.01); the main influencing factors of WAI score were RI, PSY, PE, SS, R, PHS, IS, working age, RI and the PSY had an greater effect in the score. Conclusion: 1) The monitoring of per capita annual average dose equivalent was a low-dose level, the overall health lever was better, the abnormal indicatrix should be intensively cared and observed. 2) Occupational stress of exposed group was higher than control group; with the duration of working time increased, stress lever was an upward trend; different measures should be adopted to reduce the occupational stress; the work ability of exposed group was lower than the controls, the status of work ability can be improved with enhancing personal resource, adjusting occupational stressor and improving the status of maladjustment.
